HI all. I have a linksys wireless G router connected via ethernet (NTL cable BB) to my main pc..for some reason the router went wonky last night, and i had to do a few major restarts..the pc, the router and the NTL cable set top box. Then when I reboot everything the only online page I can get is start.tnl, this is the one I used to initialy register my pc to NTLS network, had to do it again when I installed the router. However after another retart today I managed to get here..dont know how long for though.

So I guess my questions are: why did this happen? How can I avoid it again? Shall I burn it with fire?

xx

There could be loads of reasons for the network to crash temporarily.
If you are worried, ring the support line and check with them.
Don't install/upgrade anything - "if it ain't broke don't fix it".
The router is always on yeah? You should be able to access logs on the router, do they give you info?

This shouldn't really happen, it depends on how NTL have set up their authentication process. Usually an ISP uses the MAC address of the router for authentication, in this case the only reason you would have to re-register is if the MAC address changes (hence why you would have to do it with a new router). If this is the case, unless your router changes it's MAC address on a hard reset (extremely unlikely) you should never have to re-register it.

Sounds like a bit of a strange one really but it could be that one of the ISP's core routers went down and this has caused you to only be able to access internal NTL pages that do not need to pass through the downed router which is quite likely, try ringing their tech support if this happens and checking the status of their networks.

Hope this helps gg.

Thanks guys. Yeah the router is on and working, maybe it was just NTL going rse up rather than my pc?? there are still a few sites I cnt access, it just goes to NTL internal page.

This sounds like one of their routers went down then and the reason you can't access certain sites is that it takes the big internal routers some time to re-build their routing tables after certain types of errors if they have to re-build their BGP tables this will usually take a good few hours and that router will only have restricted connectivity during that period.

Ah that makes more sense, i was still connected at 100mb though. and even though I had put in my PID number it still wouldnt do anything Sad Lets see if MSN works then lol

The 100mb connection is simply the speed you get between your PC and your router, if you unplug your router from the broadband connection so you have no Internet connectivity whatsoever and plug your PC into your router it will still report a 100mb connection, your Internet connection (as it's ADSL) will be nowhere near this speed. The connection info on your PC simply represents the connection to your router which can be confusing.

ah right I see, yeah I though 100mb was a bit high, my cable is only about 1 mb

A bit of advice also.


If your internet goes down again try the following:

1. unplug the power from the router

2. unplug the cable modem or dsl modem.

3. wait ten seconds

4. power both things up in same order you disconnected,.


This kinda gives the network a wake up call as the router reaches out to make a pool of IP addresses for your network.

it also possible that someone in your area was tryng to clone your modem which would cause you to lose your cable feed for a while...

Just to be pedantic the router doesn't reach out to make a pool of IP addresses for your network, it sends out a DHCP request to get an IP address for itself, this has nothing to do with your network!

Doesn't matter, anything like a modem can be relatively easily cloned from within the same subnet, it all depends again on how your ISP's network is set up. Unfortunate but relatively simple to anyone in the know.
